Abstract

Warping is aimed at preparing the weaver’s beam to be set up on the weaving machine. In warping, the yarns are taken from the spools placed on the creel and are wound around the warp beam or roll as per the calculated width of the fabric, an uninterrupted length of hundreds of warp yarns results, all oriented parallel to one another. This paper reports a study on producing (27) yarn samples by an indirect warping machine (Benninger, Ben–Ergotronic). Samples of yarns were manufactured from continuous raw polyester filaments with three yarn counts (70,150,300 denier) under three applied tensions of (0.15, 0.22, 0.29 cN/dtex). In addition, three warping speeds (200,400,600 m/min) were used. Tensile strength and elongation at break were measured. The results of measurements of warp yarn count under study for tensile strength and the elongation under the application of the set tension and warping speeds showed optimum tensile strength at warping speed of 400m/min, under a tension of (0.22) cN/dtex. In addition, the optimum elongation percentage was at warping speed of 200m/ min, under a tension of (0.22) cN/dtex for the (70) denier yarns. For (150) and (300) denier yarns, the optimum tensile strength and elongation percentage were at warping speed of 600m/min, under a tension of (0.29) cN/dtex.
